This is basically the crux of it. You can't demand a server where the average player is level 30 and then in the next breath be upset about "epic" item commonality being unrealistic. ('You' here not being directed at anyone in particular in case that sounds accusatory.)
A demand for changes based on lore/level/power accuracy with the level 30 cap is building on the goofiest foundation imaginable. I guess you have to take the same narrative approach to your gear as you do your level. Your +4 weapon is narratively a +2, in the same way your character isn't *really* level 30.
Which yeah, the Thayans can probably crank out some +2 weapons and armor narratively so move it there if it satisfies lore/rp better than a travelling merchant.
